Abstract
The crystalline form of 4-methoxy-6-(5′,6′-dioxymethylene-styryl)-5,6-dihydro-α-pyrone is assigned to space group P212121–D24 having parameters a = 28.916, b = 8.504, c = 5.348 Å. The crystal structure was determined by the direct phasing method with the tangent formula [unk]
The refinement by the block-diagonal-matrix least squares led to a R value of 0.07 using 1501 reflections. The two ring systems of the molecule are twisted by 73°. The molecules are held together by van der Waals forces only.
